JACQUARD CARD-WIRE.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed April 3. 1907- Serial No. 366,904.

. a part'of this specification.

My invention relates to devices, known as card wires, employed tosupport on races the cards of a jacquard or other similar machine in theinterims between their passing over the cylinder of the machine.

The object of the invention is to provide a card Wire which, whilepossessing in itself means for securing it against endwise play whenoperatively attached to a series of cards, will be comparatively littlemore, if any more, expense to manufacture than the .plain straight cardwire now in common use,

secure against becoming detached from the cards, and capable of beingapplied to the cards so that either side thereof may be presented to thecylinder.

The invention will be found fully illustrated in the accompanyingdrawings, where- 1n,

Figure 1 shows several cards laced together and one of the improved cardwires attached thereto; Fig. 2 is a perspective view of the card wireshowing the manner in which it engages the lacing; Fig. 3 is a viewillustrating the card wire as it rests on the cylinder, the lacing beingshown in section; and, Figs. 4 and 5 are a plan view and a side view,respectively, of the card wire.

In the drawings, a designates the cards, I) the cylinder having the pegsc which engage with the holes (Z in the cards to cause the advancementof the series of cards, and e the usual lacing between the cards.

f designates the improved cardwire. This is preferably a plain piece ofwire having its end portions bent so as to form hooks or crotches gopening toward each other for the reception of the lacing andprojections 71. extending beyond said hooks so as to serve to supportthe wire on the race (not shown). Said hooks or crotches and projectionsare produced as follows: The end portions '1'. of

the wire are bent first back on themselves in the same plane andparallel with the bodyportion is of the wire in such manner as to leavenarrow spaces Z, each space being accessible only from the inside, i. a,from the direction of the further end of the wire. Said end-portions arethen again rebent, preferably both in the same direction with respect tothe body portion of the wire, this time outwardly and in a plane atright angles to the plane occupied by said body-portion and the firstrebend. The bending of the wire is-so accomplished that the extremitiesthereof project, after the second bending, beyond the hooks or crotches9 so as to form the projections h. The second rebends are shown in thedrawings as formed so that no spaces are left, such as the spaces Z;though this is not absolutely essential.

In assembling the wires and the laced cards, one hook of each wire isslipped over the lacing between cards and then the two cards are bentsomewhat, transversely, until the lacings are brought closely togetherenough so that the other lacing may be in like manner entered into theother hook. The hooks should be spaced apart sufliciently so that thetwo lacings will abut nicely against the hooks when entered therein andthus keep the wire against endwise movement. When thus assembled withthe cards the wires stand in such position with relation thereto thatthe cards are opposite the spaces Z formed by the hooks and, owing tothe fact that each wire is bent in the peculiar manner above described,its body-portion and the projections h Will be in planes on oppositesides of the plane occupied by the cards and lacings and equidistantfrom said plane. The advantage of this feature is that the wires may beused indifferently either side up, i. a, the body-portions above and theprojections below the lacings, or vice versa, and whether they are inthe one position or the other the lacings come the same distance fromthe face of the cylinder as the wires are passing over the latter andthe cards engage the pegs on the cylinder at the same elevation. If theprojections were arranged in a plane which was further from that of thelacings than the plane of the bodyportions of the wires, the wires couldnot be used.either side up without either making the pegs unduly long orhaving to contend with the cards more or less frequently slipping overthe pegs.

'said hook, substantially as described.

2. A jacquard card-wire having a substantially straight body portion andits endportions rebent first toward each other and forming open hooksand then rebent away from each other, the extremities of the wires'i'aeio being projected beyond the hooks to form the supportingportions of the wire, substantially as described.

3. A jacquard card-wire having a substan tially straight body-portionand its end-portions rebent first toward each other and forming openhooks and then rebent away from each other, the two rebends beingdisposed in planes intersecting each other, substantially as described.

In testimony, that I claim the foregoing, I have hereunto set my handthis 5th day of April, 1907.
